The post offers two different methods for addressing the LCD scratches, from a temporary fix involving a little petroleum jelly to a more difficult but permanent solution that involves removing the scratch and re-lacquering your monitor.

If you're using a Linux-powered laptop with limited battery life, or you just want to darken your laptop screen for whatever reason, Tombuntu has a tip for you. To turn the monitor off and have it wake up at the touch of a mouse or key, create a shortcut using this command, or type it into a terminal:sleep 1 && xset dpms force off(Note: The "sleep 1 && " portion is only necessary for terminal commands).
